To all whom it may concern.'

Be it known that we, BURNHAM C, Fri-ion` Nur and ARTHUR A. JOHNSON", both .citizens of the United States, seid S'rIcKNEY residing in Elizabeth, county of Union, and

and said JOHNSON residing` in borough oi the Bronx, county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Typewriting-lilachines, of which the following is a specification.

rhis invention relates to the manifolding function -of typewritinp,r machines, especially where certain portions of the typed matter are to be omitted from one or more of the carbon copies thereof, as', for evn ample, in the operation of typewriting an invoice Where it is desired to make a carbon record of nothing but the naine and date and total, omitting the items which 'appear in full upon the invoice.

A machine made according to the present invention preferably includes means for supporting and feeding an invoice or other outer sheet, and other means for supporting and feeding a statement or other inner sheet, and for movingr the inner sheet into position to receive the type impressions that fall upon the outer sheet. and also for moving the inner sheet away from such impression-receiving position, so that the type iinpressions will fall only upon the outcr shcet and be omitted from the inncr shoot: this Ibeing done by placing two platt-ns onc above another or in tandem relation, and movingy them broadsidc alternatively into and out of printing position, and by arranging to have the outer sheet cooperate with either platen; the inner sheet beingr arranged upon on]v Yone of said platens. l

n carrying out the present improvements, the necessary compactness of the platen mechanism and other desirable ends are secured by mounting a platen, which is revolnble for Iineiecding, and which is de signed to carry the inner sheet, above the 'other platen; said other platen being relatively diminut ve iu cross-section, and readily disposed in ou otherwise unoccupied spa/cc that occurs forward of thc feed roll which runs upon the under sido of the upper platen. Both' the lower platen and said feed roll may lio within the bend of a chutc, which may he provided for the introduction of outer sheets (for coopera-tion with either platen) into thc machine, sothat seid lower platen adds little or nothing!` to the hulk oi the typewriting machine.

This oompactncss is especially valuable in connection with the provision of a superposcd registering or collatingtable for se curing mechanically the desired registration between the inner and outer sheets, while the shccta are in position to he gripped by their respectivo fccd rolls, which therefore shall he near the tahle. The inner shect, which may he a statement. is introduced around the revoluble platen, and thence led up to the registering table, upon which it is laid and impaled, by means of perforations in the sheet, upon one or more registering! studs. upon thc tahlc. Then the outer sheetis introduced into the machine into position for coperation with either platen, and lod .up to the registering table and there registered. Before being released from the registering: pins, the sheets are clumpcd hy their respective feed rolls, and then they are in position to receive the first lino ot writing; although in some cases they may first he retracted a given number of line-spaces preparatory to thc typing opera tion; but they retain their relative positions. Other registering or colliding, meansl may ha employed.

lt is the custom to withdraw both invoice and. statement sheet from the machine, mailing the invoice to the customer but rctainingl the statement sheet, so that u )on later days it may also receive they car on rcmiids ot other invoices; the statement sheet beingr rc-inserted in the machine for each invoice until the end of .the month,

by the use of a registering or eollati'n vtahle in conjunction with means for wit'- drawing the statement from printing posi- `tion while the items upon the invoiee are `)being written, it becomes feasible to ineke ment and ledger sheets' with the items, and' without difficulty in securing the desired relative positions of the invoice and statement sheets in the machine.

The eollatingtahle, i'oi' this purpose, is placed just over the platens, hut sufficiently near to the sheet-clamping'devices to enable both the outer and inner sheets to be clamped before they are released from the eollatingtable. 'lhe .alieetfeeding or clamping ineane forthe outer sheet comprises a feeding couple arranged at the delivery .eide ol` the niaeliine in proximity to the eollating'talile. rl'he elainp lor the inner sheet mayv conr prise a` leed roll ruiming upon the under side of the revolulile platen, but not at an excessive distanee I'roni the eollatiiig-hoard, sini-e this platen, being the upper one, is in pro\iniilyr to the eollatiiig-board, and Ieine-e the small size ol the. lower platen necessitates only aeljglitiipward movement` of the plntens in order to bring the lower platen to printing position', and hence but little cleai'anee is needed between the upper platen and the eollatiiig-table. thas minimizing the entent of sheet between the eollatingpins and the feed roll on said upper platen.

l"or introducing the outer sheets, there is provided a ehule arranged at the rear ol' the platens, and extending do\\'iiwa.i'ill \r and bending` forwardly under the same and iip- A wardly in front thereofI to direct the outer 'alieet upwardly just in front of the platens, and up `to the associated feeding couple. 'l`he paper-guiding apron for the inner sheet is arranged aliove said chiite, and is directed downwardly and curves upwardly under the i'evolulile platen to the front thereof.

llinefs icing of' the inner and outer sheets inaAl he done hy a single stroke ol' the. hand of tlieopcrator. eoinprises a single. line-spacing handle and `trains-of mechanism ranfiifyingtherefrom to they revoliilile platen (wliieh eoiitrole' the inner sheet) and to the line-feeding couple which eonir'ols the outer sheet. The surface speed oli the inner and outer sheets may vary. Moreover` eaeli liuespaeing train uiai" inelude an individual line-spare regulator, so [hat variation nia)f lie seeiirial by setting the regulators as desired; l'or ex4 ample, the outer sheet niniY lie advanced a triple lille-space at eai'll operation ol' the line-spaeing handle. as in writing elieelcs` and other wide-spaced paperxiwhile the inner sheet may be advanced only a single The nieehanisiu pi'eleraliljvv up away from printingr line-s ace, so as to condense the carbon recon upon the statement or other Noord sheet.

An additional record sheet may be rw tained in posit-ion in the machine while the statement sheet` and invoice sheet are removed, to preserve carbon copies of all 0f the names and footinge which appear a on the various statement sheets, without ine 11dingr the items that are written in full upon the invoices. Preferably this condeneed record sheet feeds Iaround the revoluble platen within the statement and `leter sheets, but is held in place by clips W' le the statement and ledger iiheete are being;l removed and replacedA Being placed upon `eaid revoluble platen it receives enlythe condensed` or abridged data that are placed upon the statement and record sheets.v In some eases other data may also be laced upon both the invoice and this con( ensed record sheet, before the statement and ledger sheets are introduced into the machine. Provision is ln'eferably made for automatically advancing the condensed record sheet it linespaee after the accumulation of an entry thereon, so as to space the same from the following entry.

The revoluble platen,

in moving away from printing` position,

becomes disconiected from the line-spaeing mechanism, so

that the sheets thereon will neither be written upon nor line-spaced.

t )ther features and advantages will hereinafter appear. i

The drawin illustrate the invention in connection Witsan Underwood typewriting machine, in which a paper-carriage trav upon rails, of which one is shown at 21.

.e types 22 (which preferably are all uppercase, figure and character types, so that no case-shifting mechanism is required) strike through a ribbon 23 carried by a vibrator 24 as usual. The type impressions muy be received upon either of two platens, r of which 25 is illustrated as revolu e for line-spacing and the lower of which 26 need not be; an these platone are connected for movement to bring either one to printing position while the other one is moved away from 1printing position. For this purpose, both p atens are mounted upon a frame which swings about a shaft 27 which is journaled in the vertical sides 2S of the carriage 20. The platens 25 and 26 extend between plates 29 forming the sides of the swin ing frame, which is provided with a han le 30`mounted upon an arm 3l vextending up from one of the side plates. Said frame may have a pin 32 to engage a notch in a latch 33 to lock the frame elevated, as at Fig. 9, with the up'per or revoluble platen away from the printing point and the lower platen brought into use. The latch is provided with a finger-piece 34 for causing it to release the swinging frame, comprising the side )lates 29, and a tie-rod 35, mounted on the shaft 27 so that the frame may gravitate to normal position in which the platen 25 is at the printing point, with pin 32 resting against an edge of the carriage plate 28.

Around the rovoluble platen 25 muy be carried a record lsheet 36 and a ledger sheet 37, Fig. 6, or any other assemblage of sheets, for example a statement sheet, a ledger sheet and an interveninp,r carbon. These may be introduced into the machine by inserting them at the rear of the platen 25 and between the same and a paper-shelf or ,guiding apron 38. Fig. 8, which extends downwardly und forwardly and then curves upwardly toward thc. front of the platen, to confine the sheets lo the platen; and the sheets may he pressed against the platen by feed rolls 39 carried by means of swing arms 40 upon the tie-rod o1 shaft 35 whirh connects the side plates 29 of th e swinging frame. To permit the sheets to be introduced, between thc platen and feedroll or rolls 39, the latter may be cast olf by means of a release key, 41, Fig. 4, which may be connected tta-stock shaft 42, havin cams 43 to engage4 release arms 44 on sha 35. l

After the assemblage of sheets 36 and 37 is introduced around the platen and while the feed rolls 39 remain released from the platen, the leading portions of the sheets may be drawn upwardly from the front of the platen and re istered upd'n e. board or tablet 45. This registering or collating tablet may he mounted at any suitable place on the delivery side of the typewritinglmachine and for convenience4 is illustrated as overlying the rotary platen 25, and incliningy upwardly and rearwardly. For registering yor ing purposes, this tablet ma be provided with pins 46, and these may varranged at intervals one above another upn the tablet, to enter holes or perforations usuali formed in the side margins of the sheets. fter the sheets are thus registered upon the. pins, the release key 41 may be manipulated to restore the feed rolls 39 to effective positions to hold the registered or collated sheets upon the platen 25.

While the sheets are thus held, an'd before any other sheets are introduced into the Ina.- chine, the types ,22 may be operated to write memoranda at the top of the statement, led lrer or other sheet.

i s soon as the described sheets have been adjusted, or made ready for receiving' carhon impressions, the invoice sheet 47 is introduced, together with one or more copy sheets 48, with intervening carhons. This collatis done while the previously introduced V sheets remain stationary in the machine; and these new sheets are inserted at a different point and in rear of the record sheets, and are guided down below the same and then up in front of them, the first set or the record sheets thus orcu l)ying positions within the invoice sheet or s ieets, as seen at Figs. 8 and 6. Preferably the invoice sheets are introduced into a chute comprising a rear inclined wall 49 (which may form ari id element of the typewriter carriage) and; a front wall 50. this chute extending downwax-diy behind the shafts 2?, 35 of the feed rolls 39 on the platen 25, then curving or bendinglr forwardlv und upwardly at 5l, 51, around both the feed roll 39 and the second or fixed platen 26, as the latter lies in its abnormal position at Fig. 8.

The upper member 5() of the chute may be luv-nt upwardly and forwardly at its upper ond to form a fender 51D per edge of the apron 38 to shoots from being introduced and 38. Room is made forV tion of' 3S to turn below or within said fender, as seen at Fig. 9.

'lhc invoice set of sheets is passed readily )revent the ietween 5f) overlying the tlpthe upper pory iso f registered or collated down throih the chute forwardly beneath and upwar y in front of the platen, whence they ma be drawn up to pass through a couple o line-feedin rolls 52, 53; the positions of the parte ing such that these outer sheets are bent slightly over the platen at the rinting point, so that the sheets may be hel taut and smooth upon the platen, as at Fi 8 and 6; the roll 52 and the mouth of the chute 49, 51 bein eet a trifle back of theextreme front of t e platen 25 for this purpose. For convenience in illus-v trating the work-sheets, the platen 25 is diagrammatically shown under-sized. Its real diameter at 52, Fig. 8 would be so great as to stand substantiallv forward oi the top 51 of the chute. The upper roll- 53 of the couple is carried upon arms 54. `One or more springs 55 cause the roll 53 to bite the roll 52; but by means of a handle 56 projecting from one of the arms 54, Fig. 2, the roll or rolls 53 may be cast oil' for eonvenience in introducing the invoice sheets 47, 48, which may be pulled upwardly and by means of the usual perforations either upon the pins 46 in any desired relationship with the record sheets 36, 37 whereupon the handle 56 may be manipulated to restore the feed 'roll 53 te eoperate with the roll 52 to line-feed the invoice set of sheets 47; the feed roll 39 for the revoluble vplaten 25 having been also restored to eii'ective position.

After the feed rolls have been restored, to clamp the sheets Where registered. and before any line-feeding 'is done, the impaling pins 46 may he withdrawn by pressing a handle 57 to the right. This handle is con lieeted to a pair of cam plates 58, Figs. 2 und 8, to engage the pins 46 at the opposite ends of the eollating-table 45 to withdraw all of them simultaneously, as at Fig. 9; said cam plates 58 having suitably inclined edges or cams 59 to engage corresponding cutaways .or slots 6() in the pins 46 for this purpose, Figs. 2 and 5. The cam plates or rods 58 are connected by cross-bars 6l, (the latter may be formed upon a longitudinal slide 62) carrying finger-piece 57. The pins 46 having been withdrawn from the sheets, the line-Spacing operations may proceed.

lVhen it is desiredl to write on the invoice or outer set 47, 48, without writing upon the inner or record set of sheets 36. 37, the platen 25, carrying the latter, is first swung up out of printing position, and the lower platen 26 is simi'lltaneously swung to the printing point, as at Fig. 9. The sheets remain held against the revoluble platen 25 b v the roll 2li), and when limp sheets are used a slight portion thereof above the platen may Vforni a loop or collapse over the platen at 64. Fig. .l, although stiff sheets may ride idly up and down over the tablet 45 as the platen is raised and lowered The under platen 26 occupies a position between the side plates 29 of the swing-up frame, an may be fixed relatively to said frame. It Will he seen that it is only necessary to swing the handle 30 rearwardly and downwardly in order to bring the small platen 26 into use, as at Fig. 9, so that as many lines as desired may be written upon the Vouter sheets 47, while the sheets 36, 37 remain stationary upon the cast-oil "platen J25. Hence, a largeY number of items may be readily placed upon the invoice sheets`47, 48 without being written upen the reeol'd sheet 36 or 37.

This platen 26 may have several" faces, each one hemp,i

ilat or slightly arched, and

provision may be made for rotatiirgr t'he` platen to brin r any of these faces ntouse. t prolong the lite of the platen. It may be mounted upon a shaft 66, which is journaled A in the side plates 2'.) of the swingup frame,

and is provided with a finger-piece 67,-

whereby it may be iirst released Jfrom a lockingrr projertion 68 secured to the left-hand plate 2l) of the swing-frame and then rpotated to bring a Vl'resh face infto use, after which a spring 6th may snap,I the pl i back into loeklngg,l relatibuuwitli projeitibn 68. (.)ther types of lixed platen may be iised, and certain features of the invention1 are not limited to the useol a fixed platen! at this point. This platen may be eompaetly plm-.ed below the revoluble platen occupying but little room between thewplaten and the elude all, 51, and may lie within the bend ol' the outer sheets 4?, Figli, and` may readily be moved up t'o :I1/printingr position; it being a desideratu'rn to minimize the spare between the forward portion of the chute ou, 5l and the collatingtahle 45,

so as to permit relatively short invoices to i w n A ends ernainin be collated, while their lower said iehute. lt will be seen that placing the relatively slnall platen 26 below the revoluble platen 25 of relatively extensive eross-section, not only is desirable compactvat ness attained, but also interference with Inanipulationfnf the sheets 37 habove the Vrevolnble platen 25 is avoided.Y TheVV snilill platen 26 is located in proximity to the place where sheets are necessarily confined closely t `the large platen 25, inaccessible, that is., at the under side thereol; said small platen being adjacent to the ronlining apron 38, sothat the small platen may noutend to interfere with the nsual and hence are" the platen they pass first downwardiy at the rear ol the machine and then upwardly in front of the platense, so thatgreat compactness oi" struc ture is gained, and the necessary conveni ence ol' access for manipulating the sheets. is preserved The chute may he proviilezl at its forward or delivery orifice with light spring lingers Gt'. to press the invoice sheets against the rear face of' the chute, and hold them lightly against accidental displacement, and also causo them to cling closely to whichever platen 25 or 26 may he at the printing point. I

When it is desired to write the footing, which is to appear upon all the sheets, the latch 33 is released and the piatens 25, 9.6 are swung down with tho 'frame (compris ing the plate :39 and tie-ruil 33) ln other words, the lower platen 2G is moved away from printing position, anal the upper platcli25,with the sheets thereon, is brought; into printing position, so that saiil sheets assume print-ing relation with the invoice sheets 47, as at Figs. and G, whereby the total amount now written upon the invoice will appear upon all sheets. rfhe r n-rl upon the statement and ledger sheets n merel the name, date and gross amount3 omitting the items. saving paper, und avoids the necessity of recopying the amounts from invoices to statements or ledgers. he

laten-displacing freine may he ,linut ,l its downward movement by pin. i left-hand `late 29, and a similar pin on its riglmlmnr. late 29; the pins striking eliges upon theo'i er plates 28, as shown in Fig. R.

Aterthe writing of the total upon the invoice and all the remaining sheets. the roll* 53 may be cast oli and the invoice withdrawn without disturbing any or' the mailling sheets; or the entire invoirf; i of sheets may be withdrawn while roll Sii heli released hy detent without disturbing sheets 3G, 37. in many eahowever. the sheets 3G. 37 will lso he *ithn drawn. A fresh set of sheets 25e. iii" u fresh invoice or invoice srt ma)l na inserted2 and the writing prou-.eil as herein before set forth. The erh it. Iii" are usnaliy preserved and each set is re-insertvzl in the machine upon suecessivegilay" until the enil of the month, when iii ment sheet 36 is maiieli to the .-usioiner 'pai h reinsertion oi la set. it ma): a- F f upon the tablet l5. auf! @wir renithe fresh invoice set i?. l5 is also r or eollatell in proper position w erenee to t, whereby the opi-ration oi invoicing: uml 'lmoliireeping expwtial. Each fresh invoice is registered in tl :une position as the last. hut ai; each fresh .isi-e2 tion of the same Statement sheet, it is te; istererl or collaterl in a more advanced position upon the taille7 whereby steril-tweemaal carbon copies of .coessive invoices may fol low one another upon the statement.

When a fn wir, invoice set is to be inserted, the colA ting pins 46 are first re-pro jectefl, and both the outer and inner sets of sheets inipuiet thereon, to brin the outer sheets l? inte the required relative register with the inner sheets; and then the pins 4G are withdrawn and the operation proceeds as before.

lt will he seen that a row of the pins 46 extends upwardly at each side of the machine; and it will be understood that while there are only two pins shown in said row, still the row 'may be extended and have three, or as many more pins therein as may be desired. The advantage of the row of pins extending upwardly along one side of the machine is that they sullice to aline and register a sheet which is too narrow to reach over to the row of pins upon the opposite side of the machine; and, hence. certain of these narrow sheets may be impaled upon the lefthand row of pins, and one or more other narrow sheets upon the right-hand row of pins.

lt being usually desired to remove the statement and ledger sheet from the machine after the writing of each invoice, (since successive invoices are usually' made out to different customers, each having his individual statement and ledger sheet), the statcinent and ledger sheet in each instaure are' usually kept clipped together, unil are reinscrted in the machine ('laily or at longer intervals during the month. As the statement snrl ledge sheet gradually fill in this manner, theyr must at each insertion he collated in proper position to receive the first new line of writing just helow the last carhon entry apfearing thereon. For this purpose they are usually provided with periorstions along their side margins, whereby they may be collated @pon the pins i6 by the aid of any suitable mark or scale 70, to indicate where the sheet should be placed, in order that the first line to he written thereon shall follow properly the line written at the last previous insertion.

Preferably, the assemblage upon the revoluhle platen 25, Figs. S and 6, comprises a ledger sheet 37. a statement sheet 36 with an intervening rarhou, a carbon T2 upon said `i' nenn-nt sheet, and a transpicuous tissue sheet T3 facing or overlying the carbon 72, the letter hiring a. (loulile carbon, to make u mmf upon the transpicuous facing sheet T3 when the parts are in Fig. 8 position. Because of the provision 'for copyingr upon the trenspicuous sheet 73, the operator is at any time able to read thereon the entry that has Ewen written upon the statement and ledger sheets. As an nifl, the transpicuous sheet f2 may 'he printed .similarly to the statement slim-i llii :lltlmligjll it New! lint la' nl' :1s` g'f ula record sheet shell advance one, two or three line-spaces at each operation of the handle 74.

It will be noted that euch line-space regulntor may be set independently of the other, sind hence that the linespacng of the inner eet und outer set of sheets may be either the sume or diverse, since the outer set may have either greater or less line-space intervals than the inner set. This is en advantage where it is desired to have the outer set of sheets written with wide line-spacing, as, for instance, in Writing checks or bills, while the inner set advances with narrow linespaces, to economize the peper upon which the record is preserved.

It will be understood that elthou h both line-space trains will operate when t 1e revoluble platen Q5 is down in Working position, as at Figs. 2 end 7, said platen will not be rotated when it is up out of use, as in the Fig. 9 position, since at that time the platengear 98 is out of mesh with the pinion 97, which, therefore, rotates idl at such time. In order to avoid rotative isplncement of the platen 25 when it is up out of control of the pinion 97, seid platen may be rovided, as et its right-hand end, with e rete et wheel 100, Fig. 4, having;r e. pitch suitably corresponding with the pitch of the ratchet wheel 13; and e detent 101 may he provided upon the right-hand side plate 29 of the swing-up frame which carries the platen 25, so as to preserve the rotative position of the platen from the time it is swung up until it is swung down egizio into the control of its drive pinion 97.

At Figs. i, 8 and 9. it will he observed that the Surface speed of the rotating feed roll 52 is less thun that of the revolullle platen 25; but it is obvious that the proportions of the goers ma)v he vnried. so es to render such surface speeds simil-ur, or such as to rernler the speed ol' Q5 loss thun that ol 53." More over, the speed of line-spacing muy he varied by Setting thc regulators ditferently; :forexun'iple, one regulator ceu he set for single linc-spacing while the other is sot for tri le line-Splicing. ln some cases both means or effecting: wwiution in the feeding of the inner und outer sheets may he used, that is, the surface speed only lne made to very by means of the` gearing. und further variation muy he secured by means of the line-space regulators. us in thc form of the invention illustrated.

The` invention ie adepti-d for u wide variety of purposes, ne for further exemple it can bc used for "condensed billing or check writing, or analogous purposes. The lino-spmwing.,r regulator of the hill, check or other outer sheet 47 muy be set lor double or triplo spacing, while the line-space regulntor 9!) Jfor the irdord or other inner Sheet 37 muy lai-wt for single spewing, for cornpactness ol the record. To operate the ma chine for condensed billing or any eendensed record work, the record sheet 3T is.

An invoice is then introduced into the chute 49, 50, in the manner already de scribed, and carried down and up around both platens, and positioned by meme of the registering pins 46. The types may be operated to write the address u onthe in voice, and the duplicate tjre lmpresa'ons may appear upon the recel' sheets 37, but narrowly line-spaced. The items of the invoice may then be written until it is completed; and then the invoice may be with" drawn, and e fresh one inserted Vsind ngitered or collated ready to he written the record eet 36, 37 Y l .e rg

In some ceses it is desirable .to preserve a condensed general record of the entries made upon the successive statements referred to in the early part of the foregoing descriptifm, and for such purpose there muy be used o The puwl may he uns serted inthe machine;

record sheet 106, Figs. 8 and 6, (preferably with an overlying carbon 107). This sheet with its carbon may be introduced in rear of a. fixed member or cross-bar L08, Fig. 8, fixed at its ends upon the side plates 29 of the swingup frame. The record sheet 106, whichis to remain in the machine and preserve a carbon copy of all the entries made upon the successive inner sets 2&6, 37, may be wider thany anyof thc other sheets in the machine; and b means of its overlapping margins. it may clipped against the cross-bar or support 108, by using yielding clips 109, one at each side of the machine. The clips may be fixed upon the ends of the rock shaft 3 5, to be brought automatically into use to clip the sheet whenl the feed roll 39 is withdrawn, Fig. 8, and to release the sheet when 39 isrestored to working position, Fig. 9. It will be seen that devices for carrying this condensed record sheet. 106 are mounted upon theswing-upl frame, so that said sheet is carried ot of t e wa when the platen 26 is brought into use. l ence,- only abridged records are accumulated upon 106. A tablet 110 may also be provided upon the swingup frame, to support the sheets 106, 107 emerging at the delivery side of the machine, below the collating-table 45 and above the introductory chiites.

In using the condensed record sheet 106 for acnmulating entries of totals appearing .upon dilerent customers statements, the preferred method is, as follows: At the first insertion of the statement, the name is `written upon the invoice, statement, ledger andgcondepsed record sheets all at the saine time, together with the date. Then the platen 25 is moved up, and the items are writtenfpupon only the invoice sheet, by means of the lower platen 26. Then the platen Zzimaylie moved down again, and the total w ritten upon the invoice, the statement, the ledger sheet, and the `condensed record sheet. This operation may be Fepeated for each succeeding statement. Successive Kstateins-nts, are of course to different customers. Thus, there is kept on the condensed record sheet a daily record of the names and entries of all the invoices for all the customers. On the following day, using fresh invoice sheets, it heroines necessary tolintroduce again the same statement and ledger sheet that were used on the first (lay. lt is also necessary to write the VIlulne and address upon the fresh invoices, and it is desirable that such names should be recorded also upon the condensed record sheet 106, although it is not desired to have the name repeated upon the statement or ledger sheet. Therefore, on the second and following days, when an invoice is inserted, the name may be typed `thereon before the statement anillledger sheets 36, 37 are inthe platen 25 at the made out typewriting o leration being in its depressed position, so t at such name is also written upon the condensed record sheet l06. Then the invoice is inserted, and the date is written to appear upon all the sheets. Then the platen' 25 is swung up out of printing position, and the itemsl are written upon the invoice sheet 47 bythe use of the lower platen 26; whereu ion the platen 25 is swun f down again, and t 1e total is printed upon alii the sheets. The condensed record ysheet 106 may be in the form ol a web if desired.
